Fiat,
I am confused, I thought Purple was pretty detailed in her explanation (no offense) and her first sentence states what she thinks. "No plant likes to be rootbound." She also mentioned you need to be sure you don't put it in potting mix that's going to cause it to rot. I read it as, you should give it room to grow, but make sure you put it in as potting mix that's fast draining and won't stay wet too long.
If you need advice on a potting mix, there are several "schools" of thought on that. There's the Gritty Mix, the 5:1:1 mix, and some people mix up their own potting mixes (like myself). I mix up Miracle Gro Cactus and Palm potting mix with rinsed perlite (a ratio of about 50/50). Be sure to rinse the perlite, as it has excess fluoride in it which a lot of plants are sensitive to. I will say that from reading about different mixes, what makes the Gritty Mix ideal is it has large particles (something else Purple hit on, too small of particles in your mix won't allow the roots to breath and they can rot), but it requires more frequent waterings due to that. I think the 5:1:1 mix is more for tropical plants ('Peace Lilies,' stuff that cannot handle drying out like the Gritty Mix does).
My mix is not perfect, but amending the store bought stuff (as Purple also hit on) will help.
You have beautiful plants, but I wanted to express one concern. That last one, the 'Gold Hahnii' (if you didn't know this already), is known for it's fussiness. Hahniis in general are a little more difficult to care for than the other types (such as 'Futura' in your second photo, or the tall one in your first). This one I've read requires no water in winter. It may look like it needs a drink, but it is extremely susceptible to rot in the winter. That one may or may not be overpotted. How big was the root system when you planted it over? Again, with their susceptibility to rot, that is the only one that concerns me (repotting wise).
If you ever have any questions about Sansevieria, Stush2019 has been growing them for longer than I've been around (I've been around a while if that says anything). There are a ton of folks on this forum that know a lot about plants (so I'm not saying you should soley ask him questions), Sansevieria included, but Stush could tell you in more detail certain things I cannot.
I hope this helps.
